or DE KALB, ILLINOIS.

To all whom it may Concern 1 Be itknownthat I, lVIAR'rIN E. ANDERSON, acitizen of the United States, residing at De Kalb, in the county ofDekalb and State of Illinois, have invented certain new and usefulImprovements in Wagon-Scales, of which the following is a specification.

My I invention: has reference to Wagon scales, and relates morespecially to novel mechanism by means of which the weight of the load,which is under normal conditions carried by the main frame of themachine, is transferred to the weighing devices, to be suitablyindicated thereby.

In the drawings, Figure 1 is a plan view of my invention. Fig. 2 is anenlarged detail of the lever 8 and connecting mechanism at one sidethereof. Fig. 3 is a detail of the scale mechanism, in side elevation.

I represents the frame of the machine, which may be portably supportedin the manner shown in companion application filed by said Martin E.Anderson on the twentieth day of November, 1914:, for improvements inwagon scales, Serial No. 873,229. The load is normally supported bymeans of bolsters 2, resting at their ends on the side-pieces of theframe 1. Pivoted in the sides of the frame 1, as at a, is a pair oflever-frames3, having short outer arms 4 adapted to be operativelyconnected with the bolsters 2.

Fixed to the side-pieces of theframe 1, centrally thereof, is a pair ofbars 5, secured to which is a pair of brackets 6, between which isfulcrumed a lever 7 as at 6, projected outwardly beyond the frame 1 andprovided with a handle '8. The short end of the lever 7 is connected bymeans of a pair of links 9 with the ends 10 of said frame levers 3, suchends being reduced so as to engage perforations 11 said links.

Fulcrumed on the side of the frame 1, as at 0, is a scale-beam 12,depending from which is a guide-frame 13, in which the outer end of thelever 7 can be moved up or down. The frame 13 is provided with a pair ofrecesses 14, with which the lever 7 is operatively connected by means ofa pin 15 fixed in the lever 7 and projecting beyond each side thereof.When the outer end of the lever. 7 is forced upwardly it results in adownward movement of the inner ends of the levers 3 and an upwardmovement of the in the upper ends of "Specification of Letters lat'ent.

WAGON-SCALE.

' short ends 4: thereof, sufficiently to elevate the -bolsters, 2 ashortdistance above the frame 1. The load carried by such bolsters isthereby; transferred from the frame 1 to the lever frames 3, and isimparted through the lever-7 to the weighing devices, whereby Iindicated, the lever and it can be properly scale being connected up asshown in Fig. 2'. After the load is weighed the lever 7 is raisedsufficiently to permit a release of'the pin 15 from the recesses '14,and the lever lowered into the position shown in broken lanes. Thedownward movement thereof is limited by the frame 13. When in the latterposition the inner ends of the frames 3 are again raised and the outerends lowered, permitting the bolsters 2 to again rest upon the frame 1.

The ratio of length of the long and short arms of the frames 3 isapproximately 10 of the long arm to 1 of the short arm, and theproportions of the long and short arms of the lever 7 are about thesame, so that an upward lift of thirty pounds on the handle 9 will besuflicient to raise a load of three thousand pounds on the short arms 4.All of the pivotal points are preferably provided with knife-edgebearings, so as to reduce the friction to a minimum.

There has been shown and described herein the preferred form of myinvention, but variations and modifications can be made therein withoutdeparting from the spirit of the invention.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, is:

1. A wagon scale, comprising a suitably mounted frame; load-carryingmeans normally supported thereon; a pair of frame levers fulcrumed insaid frame, adapted to engage said load-supporting mechanism at theirouter ends, and having their inner ends in proximity at a central point;a hand-lever connected with the inner ends of said framelevers; weighingdevices mounted on said frame; and means for detachably connecting theouter end of said hand-lever with said weighing devices to impart theweight of the load thereto.

2. A wagon scale, comprising a suitably mounted frame; load-carryingdevices normally supported thereon; frame-levers fulcrumed in saidframe, adapted to cooperate with said load-carrying devices at theirPatented Jan. 25, 191s. Application-filed November 30,1914, Serial No.874,585.

short ends; a hand-lever operatively connected with said frame-levers;weighing devices mounted on said frame; and a frame depending from saidweighing devices and provided with means for holding said weighingdevices in operative connection with said hand-lever when saidframe-levers are in engagement with said load-carrying devices, to holdthe same in elevated position.

3. A wagon scale, comprising a portable frame; load-carrying devicesnormally mounted thereon; frame-levers fulcrumed in said frame, adaptedto cooperate with said load-bearing devices at their outer ends, andhaving their inner ends in proximity at a central point; a hand-leverfulcrumed cen trally of said main frame and operatively connected withsaid frame-levers; a scalebeam fulcrumed on the side of said frame; anda frame depending from the short arm of said scale-beam and adapted tocooperate with said hand1ever when such hand-lever is in an operativeposition to cause a raising of the load above said main frame.

In testimony whereof I aflix my signature in presence of two witnesses.
